MOSCOW, Aug. 24 (Xinhua) -- Two officers were killed and two others wounded
in an attack on a Russian armored vehicle in Chechnya Saturday, a source in
Russia's law enforcement services said Sunday.

"Two explosive devices were blown up as an armored personnel carrier was
driving along a road not far from the village of Agishty in Shali district. The
bombing was accompanied by fire from small arms," the source was quoted by the
Interfax news agency as saying.

Two deputy commanders of an armed forces unit, a lieutenant colonel and a
major, were killed, and two other officers were seriously wounded and
hospitalized, the source said.

Another source in the criminal investigation service said the squad, which
was part of the Interior Ministry forces, had returned fire.

The authorities have opened an investigation into the incident and measures were
being taken to identify and arrest the attackers, the source said.

Kremlin launched two military campaigns against Chechen separatist forces
in the 1990s and the early 2000s. Although the operation has almost been
completed, frequent attacks by militants still occur in the North
Caucasus republic.
